PHYLLOSCOPUS NITIDUS. 
specimens collected at Futteghur and at Etawali. About tlic Sambhur Lake Mr. Adam says that it is very 
rare; and it has only lately been added to the avifauna of Sindh, having been procui’ed at Kotri by a collector 
of Mr. Blanford’s. But there is much more still to be learnt about the distribution of this tiny Warbler. The 
extraordinary fact of a specimen of it having been shot in Pleligoland some years since proves that it must 
breed in Western Siberia. Many species, singularly enough, after breeding in Northern Asia stray, on their 
migration back, westwards through Europe till they find their way to the little island of Heligoland ; and 
this example of the Green Tree-Warbler must have been, as Mr. Seebohm infers, loc. cit., a young bird which 
had got out of its track. 
Habits . — This species frequents the upper branches of umbrageous trees, no matter whether they may 
be situated in busy thoroughfares or in the quiet of the forest. It is especially fond of Jack-trees, which are 
mostly found in the gardens of the natives, and again is very partial to the monarchs of the forest which 
surround the many romantic tanks of the interior. In these spots its perpetual little chirrup invariably 
discloses its presence when otherwise it would certainly be passed over in the lofty foliage which it frequents. 
It affects the leaves of trees more than the next species, and darts out from its place of concealment on various 
insects, after the manner of a Flycatcher. It is very lively in its actions, and is sociably inclined, for one 
or two of its fellows may usually be found in an adjacent tree, each answering the other with its cheerful little 
note. Its flight is swift, although its powers of locomotion are not much brought into play after it once 
locates itself in its winter quarters ; it then merely darts from tree to tree, and often remains for a considerable 
time without moving out of its retreat. The powers of wing which these little Phylloscopi have are marvellous; 
that they should be able to make their way across such a chain of mountains as the Himalayas, as some of 
them undoubtedly do, is one of the greatest wonders connected with the migration of birds.
